 For instance, if control points are  `(0,0)`, `(0.5, 1)` and `(1, 0)`, the equations are:
 
-- <code>x = (1−t)<sup>2</sup> * 0 + 2(1−t)t * 0.5 + t<sup>2</sup> * 1 = (1-t)t + t<sup>2</sup> = 1</code>
+- <code>x = (1−t)<sup>2</sup> * 0 + 2(1−t)t * 0.5 + t<sup>2</sup> * 1 = (1-t)t + t<sup>2</sup> = t</code>
 - <code>y = (1−t)<sup>2</sup> * 0 + 2(1−t)t * 1 + t<sup>2</sup> * 0 = 2(1-t)t = –t<sup>2</sup> + 2t</code>
 
 Now as `t` runs from `0` to `1`, the set of values `(x,y)` for each `t` forms the curve.
